To be fair, he judges "the draft process" not "the players."
Kiper wrote that the Seahawks could have drafted Bruce Irvin and
Bobby Wagner later on, and that they didn't really need Russell
Wilson since they already had Matt Flynn. All of that is probably
true.

Sports Illustrated's Chris Burke gave them a C.
He called the Irvin pick "spit take-inducing" and
wrote, LB "Bobby Wagner (47) and RB Robert Turbin
(106), both from Utah State, will help, and QB Russell Wilson
(74) has a bright future, even if Seattle didn’t really need him.
Everything else was … very … blah."

The NFL Network team of analysts gave them a
C. Michael Lombardi criticized them, saying they took "a
lot of chances."

Irvin, Wagner, Jeremy Lane, and Daye Howard are significant
players on defense, Wilson has been a revelation, and running
back Robert Turbin is #2 on the depth chart behind Marshawn
Lynch.

It was a homerun draft.

Again, these draft experts have a basically impossible job.
But this should at least make us take draft grades with a bit
more salt.
